gpu - High Temperature when stress testing Intel Core i7 3770K

    I have bought an i7 3770K. I have tried to stress it, N

    ear full load computation using CUDA I was surprised that it gets 99°C at 68% of the CPU load, is this normal? I have to change the cooling system?

    I use a Cooler Master Hyper TX3 cooling (that is for i5 maybe). Should I use the normal fan sold with the CPU?

    On Idle my CPU too is in the gap 32°-38° C the problem is under stress (only 68%) and I'm not overclocking the system!

    The problem could be due to the GPU? But I have checked and I don't think so.

    You will probably want to check a few things to see if this is causing the High CPU Temperatures.

    1. Make sure that you used Thermal Paste
    2. Don't use too much. A drop or two is sufficient. A paper thin spread is ideal.
    3. Clean any excess paste around CPU and Heatsink with Qtip and Denatured Alcohol. If you have paste that is overflowing, the heat cannot dissipate properly.
    4. Make sure that you have a solid connection with the heatsink.
    5. Make sure that the heatsink is receiving proper ventilation. (free of dust bunnies)

    I have the Coolermaster N520 on my Ivy Bridge Core i7 and idle it will run about 32c.

    I needed to do a small video compression today and took a snapshot of the CPU load and CPU temperature. With a large CPU load, it still was about 35c-37c.

    laptop - CPU Core Temperature Variation
  • William Lawn Stewart

    I have a brand new laptop with an i7 2630QM CPU. Core #3 (Out of 1-4) always has a temperature 3-8C cooler than the other cores under normal operation. If I put 100% load on the core then it'll go up to the same temperatures as the other cores. Loading a different CPU core results in a 10C difference.

    It seems to me that the temperature sensor for that core is off. Considering how small the CPU is, I seriously doubt that core #3 could have better cooling.

    Should I be worried about the fact that one of the temperature sensors is inaccurate? (assuming it is inaccurate?)

    The difference isn't much of a concern. But then again, you never posted the actual temperatures. The actual temperatures make more of a difference than the temperature differences.

    My guess is die defects. It's common to have cores at different temperatures as long as they pass the stability test.

    I wouldn't concern myself with it. Life is too short to concern yourself with arbitrary temperature differences.

    Do you mean Core #3 as in 0,1,2,3 that three? If so then this may explain it:

    If you look at a the die map of a Sandy Bridge CPU you will see that the graphics hardware is right next to core #3, with #0 all the way to the right.

    If you mean 3 out of 1,2,3,4 then I have no idea.
